The three primary papers in this special issue explore personality measurement in both directions, that is, more narrow and specific and more broad and heterogeneous. The first paper reviews research on conditional reasoning, with a focus on the construct of aggression. Next, tolerance for contradiction is explored, which is defined as a mode of thinking that accepts and even thrives on apparent contradictory information. The last primary paper covers core self evaluation, which combines measures of four traits: locus of control, self-esteem, generalized self-efficacy, and emotional stability. The special issue concludes with provocative and insightful critique and commentary of the three primary papers. It notes some important points of criticism, but is primarily positive and laudatory of these research programs.
